Rolex crafts its white gold in its Plan-Les-Ouates foundry using a complex process that ensures exceptional purity and homogeneity. By alloying yellow gold with nickel or palladium, Rolex achieves the bright, white hue that defines its white gold, which is now known for its durability, corrosion resistance, and ability to retain its colour over time. This resilient material is low-maintenance and integral to various Rolex models, elevating the brand's craftsmanship and sophistication.

Once the sunray finish is complete, Rolex applies the grey colour using Physical Vapour Deposition or electroplating, followed by a light coat of varnish to enhance the dial's elegant, refined appearance.
